The hand-held machines are the source of many nuisances that can lead to occupational diseases and occupational accidents.
These risks must be identified and evaluated in order to design safer machines and improve their conditions of use.

Long term occupational exposure to Whole-Body Vibration (WBV) is a cause of Low Back Pain (LBP) for seated drivers. Poor and long term seated postures are considered as a cofactor in the risk. It depends on the vehicle’s ergonomics and tasks. Differences…

Mobile machine drivers are regularly exposed to vibration or shocks transmitted to the whole body through the seat and cabin floor. INRS studies were carried out to develop a general approach for assessing the vibration risk.

To reduce operators exposure from electromagnetic fields of old design high frequency welding machines, a technical measure consisting of the installation of a so called "grounding pad" device can be envisaged. This document was mainly written…

One out of four handheld or hand-guided vibrating tools is a percussion tool. They expose operators to high levels of vibration with a strong probability of such levels exceeding the regulatory threshold values whenever the daily exposure…

The use of some hand held tools may be the cause of bone and joint, vascular or neurological troubles due to vibration exposure.
A study lead by INRS with the Carsat assistance will facilitate the assessment of vibration risk without measurement…

Outline of reasons and objectives
Prolonged exposure to whole-body vibration increases the risk of low-back pain problems. In France, 3 million mobile plant operatives who work in the sitting position may be exposed to this type of stress (drivers…

Outline of reasons and objectives
Industrial applications based on the physical properties of electromagnetic waves can expose operators to high levels. In 2011, INRS published the results of a study based on measurements at 600 work stations…

Seated mobile machinery operators are exposed to whole-body vibration (WBV) that may lead to low back pain (LBP). The procedure defined by ISO 2631-1:1997 for the evaluation of vibration does not take into account the physical stress caused by maintained…
